Description

Multicasting Method of Broadcasting Line in Transmission Device

The present invention relates to a transmission apparatus, and more particularly, to a technology capable of simultaneously transmitting to a plurality of subscribers in one port when transmitting broadcast line data through the transmission apparatus.

The data transmission method of the conventional transmission device used a POINT TO POINT method for 1: 1 connection of the channel connection between the trunk trunk line and the local trunk line. In other words, in a public network using a dedicated line (T1 / E1), a channel (for example, 24/30) is connected to a trunk line of a local station with the concept of a local station and a large country, and the same number of channels are connected to an adjacent large trunk line. Used. Therefore, in the case of a broadcast subscriber, if a conventional method of transmitting the same data to multiple regions at the same time through a single line is used, the number of outgoing ports must be increased by the number of subscribers to transmit the same broadcast line data through the same line. And increased the number of trunk lines the user would have to occupy.

Therefore, in order to transmit the same broadcast line data through the same line by using the POINT TO POINT (1: 1) method, the transmission line data transmission method of the conventional transmission apparatus requires an outgoing port as much as the number of subscribers, thereby increasing the number of trunk lines. Therefore, there was a problem that the channel efficiency is lowered.

Accordingly, an object of the present invention is to provide a method for implementing multi-broadcasting of a broadcast line in a transmission apparatus capable of simultaneously providing a service to a plurality of subscribers through one outgoing port.

In order to achieve the above object, the present invention provides a 1: multi-subscriber multicasting method of a broadcasting line in a transmission apparatus having a switching unit connected between a trunk and a plurality of subscribers and simultaneously switching a plurality of subscribers to a specific channel of the trunk. A method of pre-setting various channel connection conditions according to the multicast service, a process of establishing a system information database by receiving various information of a broadcasting line from an operator, and a broadcasting line port after the system information database is established. Satisfies the process of activating and deactivating a broadcast line for determining whether the channel satisfies an activation condition, and if the broadcast line satisfies an activation condition, satisfying the channel connection condition for connecting to a specific channel of a trunk line to which the broadcast line is connected. The process of checking whether When the channel connection is satisfied, a process of performing a multicast to a plurality of subscribers by switching a broadcasting line to a specific channel of a corresponding trunk line.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention, such as specific processing flows. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. Detailed descriptions of well-known functions and configurations that are determined to unnecessarily obscure the subject matter of the present invention will be omitted.

1 is a hardware diagram for implementing a 1: multiple subscriber multicasting function according to the present invention;

1: According to the present invention, a switching unit 12 is configured between one trunk line 10 and a plurality of subscribers 20 for multi-broadcasting of multiple subscribers, so that the switching unit 12 performs unidirectional / bidirectional switching. There are two types of switching, call-only switching and receive-only switching. The unidirectional or bidirectional switching control is determined by operator software.

2 is a block diagram diagram of a software flow for performing multiplexing broadcast according to the present invention.

The Operator Interface Part (hereinafter referred to as OIP) 110 is an interface that receives various types of information on a broadcasting line set by an operator and outputs the information to the SYSTEM MANAGEMENT PART 120 (hereinafter referred to as SMP).

The SMP 120 makes a system information database of various types of information on the broadcasting line received through the OIP 110.

CALL CONSTRUCTION / REMOVAL PART 200 includes an active / inactive determination unit 210 for determining whether a broadcast line port is active or inactive, a switching unit 220 for switching a broadcast line to a specific channel of a trunk line, and a broadcast line. It consists of a multiplexing buffer 230 that records / manages various information such as connection conditions and connection characteristics.

One preferred embodiment of the present invention will be described with reference to FIGS. 3 and 4 with reference to FIGS. 1 and 2 described above.

3 is a control flowchart for multiplexing broadcasting in a transmission apparatus according to an embodiment of the present invention, and will be described for each step operation;

In step 301, when the operator sets various types of information of a broadcasting line through a keypad, which is an operator operation command unit (not shown), the operator receives the information through OIP 110.

In step 302, when various pieces of information of a broadcasting line are input to the SMP 120 through the OIP 110, a system information database is constructed using the input information.

In step 303, if the system information database is constructed as described above, the call establishment / release unit 200 determines whether the broadcast line port is activated. If the condition for activating is satisfied, step 305 is performed.

In step 304, the broadcast line is a deactivation condition that does not satisfy the activation condition. In this case, an error message according to deactivation of the broadcast line port is processed. The error message processing refers to a function of informing an operator that a broadcast line port is in an inactive condition through a message.

In step 305, when the broadcast line satisfies the activation condition, it is checked whether the following connection condition is satisfied before connecting the broadcast line to a specific channel of the trunk line to which the broadcast line is connected. The following are the channel connection conditions.

1. Are other broadcasting services already used for the channel you want to connect to?

2. If no other broadcasting service is used, are there enough free channels for the current broadcasting line?

3. If another broadcasting service is already used, is the broadcasting service you are using the same type as the broadcasting service you are currently planning to use?

4. If broadcast service is the same kind in 3, are the same characteristics as broadcast line to be connected?

5. Has multiplexing been specified within the multiple buffer size if the same characteristics satisfy the above 4?

If all of the channel connection conditions are satisfied, the process proceeds to step 307, and if not satisfied, the process proceeds to step 306.

In step 306, when the channel connection condition is not satisfied, the operator does not meet the channel connection condition. Therefore, an error message processing is performed to review the connection condition.

In step 307, all channel connection conditions are satisfied. At this time, the switching unit 220 switches the broadcast line to a specific channel of the trunk line and multicasts the broadcast line to a plurality of subscribers.

4 is a diagram illustrating a function for connecting / disconnecting a broadcast line to a specific channel of a corresponding trunk line according to an embodiment of the present invention, and confirming whether to connect data transmitted from a transmission port to a subscriber by the channel connection condition. The call is established and released only when all channel connection conditions are satisfied.

In step 410, it is checked whether another broadcast service is already used for a specific channel of a trunk line designated by the broadcast line operator. The operation after the check result is divided into a flow process a (steps 412 to 415) and a flow process b (steps 422 to 426).

First, in step a (steps 412 to 415), the step 412 is a case where no other broadcasting service is used for the corresponding channel. Step 413 selects Tx switching if the broadcast line is exclusively for transmission, and selects Rx switching if the broadcast line is exclusively for reception, and then occupies the channel of the designated trunk line. Step 414 buffers sub-channel values of the broadcast line according to transmission only and reception only. At this time, the size of the buffer can be arbitrarily adjusted and buffers various data of the broadcasting line. Thereafter, step 415 buffers the broadcast line multiplexing while the operator selects a subscriber to multicast.

Looking at the flow of step b (steps 422 to 426), step 422 is a case where another broadcast service is used for the corresponding channel. In step 423, another broadcast line occupies the corresponding channel. For example, a subscriber A has occupied a corresponding channel to broadcast. In step 424, if the channel of the same trunk line is to be designated under the conditions of steps 422 and 423, it is determined whether the characteristics of the broadcast line (the subscriber named A) that are already the same as the characteristics of the broadcast line to be connected now. do. The identity of the characteristics of the broadcasting line means that if the subscriber A is occupying a channel with a speed of 10K, another subscriber (broadcasting line), for example, a subscriber B and C is connected to the same channel to perform multicasting. In this case, the B and C subscribers should have the same speed characteristics as the A subscribers. If the identity of the broadcast line to be connected to the already designated broadcast line is confirmed, step 425 determines whether the multiple connection can be designated within the available size of the multiple buffer. Step 426 is a case where all of steps 422 to 425 are satisfied, and if multiple connections can be specified within the available sizes of the multiple buffers, Tx switching is selected if the broadcast line is exclusively for transmission, and Rx switching is selected if the broadcast line is exclusively for reception. The sub-channel value of the broadcast line is buffered. At this time, the size of the buffer can be arbitrarily adjusted, and the operator selects a subscriber to multicast and buffers the broadcasting line multiplexing.

In brief, the present invention; The present invention connects the switching unit to the trunk and the subscriber to connect the data from one transmission port to a plurality of subscribers to be serviced in a specific channel of the receiving trunk line to switch a plurality of subscribers to a specific channel of the trunk line, Also, for efficient channel management, various situations according to the multicasting service are programmed by software to search for the condition according to each situation and perform the corresponding multicasting service only when the condition is satisfied.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention has the advantage of reducing the cost of operating and maintaining the transmission equipment by increasing the number of service subscribers that can be connected to the same PATH by one transmission apparatus in the transmission apparatus.

Another advantage of the present invention is that by connecting several subscribers to a specific channel of the trunk line, it is possible to use a pre-channel that can provide different services, thereby enabling efficient use of the channel bank.

Another advantage of the present invention is to lower the line price to those who provide a variety of services using the transmission device.
